# The page checks a policy with wasm that scripts/build-policy-wasm.sh writes
# into policy-site/public/wasm/, and draws its background with wasm that
# scripts/build-policy-anim-wasm.sh writes beside it. Vite copies that
# directory into the build untouched, so both run first. The tests run last, against the built tree; among them,
# policy-site/tests/check-csp.mjs holds it to the CSP in
# infra/policy-site/main.tf.
